Question

A circular loop of radius \(R\) lies in which plane, with its axis along which coordinate axis?

Options

• The \(y\)-\(z\) plane, with the axis along the \(x\)-axis

• The \(y\)-\(z\) plane, with the axis along the \(y\)-axis

• The \(x\)-\(y\) plane, with the axis along the \(z\)-axis

• The \(x\)-\(z\) plane, with the axis along the \(y\)-axis

Answer 1

The loop is centred at origin \(O\) and lies flat in the \(y\)-\(z\) plane. Its axis is the \(x\)-axis, and point \(P\) is at a distance \(x\) from the centre.
